Integration Testing for Subscriptions

[andrewphillipo]

Am I correct in saying that apollo-server-testing currently does not support subscriptions into a graphql server? It would be really useful to support this; subscriptions are things that feel quite brittle and prone to people accidentally breaking them as they are transient - i.e. if you receive a notification it should change the UI under that even not before, so it is not immedately apparent that you have broken something. Maybe I'm misunderstanding but how do I go about writing integration tests in the same way as for mutation and query?

The expected behavior is I should be able to create a subscription that can be mocked with apollo-server-testing, event fired from it and I should receive the mocked notification/subscription event in my components.

I guess this is somewhat of a feature request! Thanks for the amazing work you guys do on Apollo!

This would be nice

Direct subscriptions integration was removed from Apollo Server in v3 last year. (Partially because of how the old flimsy integration led to problems like this one.)
